See r600_dpm_get_vblank_time() in r600_dpm.c for the formula: line_time_us = (mode.crtc_htotal * 1000) / mode.clock; vblank_lines = mode.crtc_vblank_end - mode.crtc_vdisplay; vblank_time_us = vblank_lines * line_time_us; -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
